The semen does not swim anything as we thought they did, new studies have found



Under a microscope, human sperm seem to swim like buzzing eels, tails swirling back and forth as they search for an egg to fertilize.

But now, new 3D microscopy and high-speed video reveal that sperm don’t swim at all in this simple, symmetrical motion. Instead, they move with a rotating rotation, which compensates for the fact that their tails actually beat on one side only.
